EPF6024AQI208-1N - FLEX 6000 24K FPGA 208-PQFP | Altera
The Intel (Altera) EPF6024AQI208-1N is a member of the FLEX 6000 family of SRAM-based, loadable programmable logic devices, delivering up to 24,000 typical gates (16,000 usable gates) in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) surface-mount package. It is supplied from a 3.0 V to 3.6 V rail with 3.3 V nominal VCC, supports industrial operating temperatures, and reaches maximum internal clock frequencies around 172 MHz in the -1 speed grade. A Field-Programmable Gate Array (FPGA) is a programmable logic device (PLD) that combines thousands of configurable logic elements (LEs), embedded memory blocks, and programmable interconnect into a single semiconductor die. FPGAs sit at the top of the programmable logic hierarchy (PLD -> CPLD -> FPGA -> SoC FPGA) and are used as glue logic, accelerator fabric, and prototyping platforms between discrete 74-series logic and full custom ASICs. The FLEX 6000 family targets cost-sensitive glue-logic, bus-interface, and control-plane applications where small gate counts and 5.0 V-tolerant I/O previously dominated. Key features of the EPF6024AQI208-1N include 1,960 logic elements (LEs), a 4,608-bit embedded SRAM, 171 user I/O pins, and four phase-locked loops (PLLs) for on-chip clock synthesis. The -1 industrial speed grade is offered in a -40 C to +85 C temperature range with 208 gull-wing PQFP leads on a 28 mm x 28 mm body. The device is built on a 0.42 um CMOS SRAM process and is configured via a serial configuration EPROM at power-up. Architecturally, FLEX 6000 devices use a row-and-column LAB (Logic Array Block) structure with continuous FastTrack interconnect that routes signals horizontally and vertically at every LE. This fabric provides predictable timing for synchronous state machines, FIFO controllers, and bus-bridge logic. The four embedded PLLs support clock multiplication, division, and phase shifting across the 171 I/O, simplifying designs that require multiple clock domains from a single reference oscillator. Typical applications include industrial control and factory automation backplanes, telecommunications interface cards, legacy PCI/ISA bus bridges, military and aerospace upgrade programs, and educational FPGA lab kits. The wide-package 208 PQFP footprint makes the EPF6024AQI208-1N particularly attractive for redesigns of older PLCC-84 systems that need more I/O and embedded memory without moving to BGA. When designing with this device, allocate sufficient PCB area for the 28 mm x 28 mm PQFP body and use a 4-layer board with a dedicated VCC plane. Decoupling requires at least one 0.1 uF ceramic per VCC pin plus a single 33 uF tantalum bulk capacitor within 25 mm of the package. Boundary-scan (JTAG) and a ByteBlaster or MasterBlaster download cable are supported for in-system programming through the dedicated nCONFIG, nSTATUS, CONF_DONE and DCLK pins.

EPF6024AQI208-2 - FLEX 6000 PLD 24K Gates 208-PQFP | Altera
The Altera (now Intel) EPF6024AQI208-2 is a loadable Programmable Logic Device (PLD) from the FLEX 6000 family, fabricated on a CMOS process and packaged in a 208-pin Plastic Quad Flat Pack (PQFP, code QFP208,1.2SQ,20) with 0.500 mm terminal pitch. It delivers 24,000 usable gates, 1,960 logic elements (LEs), and 171 configurable I/O lines plus 4 dedicated inputs, organized as 171 inputs and 171 outputs for high-density glue-logic integration. What is a PLD? A Programmable Logic Device is a generic term for a digital IC whose logic function and interconnect are defined after manufacture by the end user. PLDs sit within the broader taxonomy of programmable logic: simple PLD (SPLD, e.g. PAL/GAL) -> complex PLD (CPLD) -> field-programmable gate array (FPGA), with FPGAs occupying the highest density tier. The FLEX 6000 series occupies the CPLD/early-FPGA boundary, optimized for high I/O count and predictable timing rather than register-rich datapath synthesis. Key features of the EPF6024AQI208-2 include a maximum clock frequency of 153 MHz, in-system programmability via SRAM configuration cells (requiring a configuration device on power-up), 5 V tolerant I/O (the 'I' speed grade), and an industrial operating temperature range of -40 C to +85 C. Embedded array blocks (EABs) provide on-chip ROM/RAM for look-up tables and small FIFOs, while each logic element contains a 4-input look-up table and a programmable flip-flop. Architecturally the FLEX 6000 uses a continuous-routing FastTrack interconnect that delivers predictable, compiler-driven delay rather than the segmented routing of later FPGA families. This makes timing closure straightforward at the cost of slightly higher propagation delay per gate compared with Look-Up-Table FPGAs of the same vintage. The PQFP-208 footprint offers through-hole-compatible hand-solderability for prototype and legacy repair, in contrast with the BGA-only options of later Cyclone families. Typical applications include industrial glue logic replacement, bus-interface bridges (e.g. PCI/ISA to local microcontroller), motor-control state machines, legacy telecom backplane glue, and instrumentation front-ends where 5 V I/O tolerance simplifies interfacing to analog front ends. The high I/O count (171 user I/O plus 4 dedicated inputs) suits designs that previously required multiple 84-pin PLDs. When designing with this part, note that FLEX 6000 devices are SRAM-based and lose configuration on power-down; pair with an Altera EPC configuration PROM (EPC1441/EPC1) for non-volatile boot. The PQFP-208 package requires a 1.2 mm pitch PCB footprint with a 30.6 mm body and exposed lead fingers - allocate at least four PCB layers for clean power and ground return paths beneath the package.

EPF6024AQI208-2N - FLEX 6000 24K Gate FPGA, PQFP-208 | Altera
The Altera EPF6024AQI208-2N is a member of the FLEX 6000 family of CMOS SRAM-based programmable logic devices (PLDs), featuring 24,000 typical gates, 1,960 logic elements, and 171 user I/O pins in a 208-pin Plastic Quad Flat Pack (PQFP) package. Per the Altera FLEX 6000 datasheet, the device operates from a 3.3 V core supply with a maximum clock frequency of 153 MHz, and uses SRAM configuration cells that must be loaded at every power-up from an external serial or parallel memory device. A FLEX 6000 device is a fine-grained reprogrammable logic IC that sits between a complex programmable logic device (CPLD) and a high-density field-programmable gate array (FPGA) in the broader programmable logic hierarchy (CPLD -> FLEX 6000 -> FPGA -> SoC FPGA). The FLEX 6000 family was Altera's first Optically reprogrammable, low-cost, SRAM-based FPGA line optimized for high I/O count glue logic and data-path applications. Compared with CPLDs, the FLEX 6000 offers higher register density and richer routing; compared with modern FPGAs, it provides simpler development but lower logic capacity. The EPF6024AQI208-2N delivers 171 configurable I/O lines plus 4 dedicated inputs, supporting a wide range of I/O standards including 3.3 V LVCMOS/LVTTL on the I/O banks. The maximum toggle performance of 153 MHz makes it suitable for mid-speed peripheral controllers, bus bridges, and state-machine replacement. Its high I/O count relative to its logic capacity makes it ideal for I/O-intensive glue-logic designs rather than DSP-heavy workloads. Internally, the FLEX 6000 architecture combines Look-Up Tables (LUTs) for combinational logic with dedicated register cells, interconnected by a continuous FastTrack routing matrix. The device uses SRAM configuration cells, meaning configuration is volatile and must be reloaded from external non-volatile memory (typically an EPC configuration EPROM) on every power-up via the Altera passive serial (PS) or passive parallel asynchronous (PPA) configuration scheme. Typical applications include bus-interface bridges, peripheral controllers, industrial I/O expansion, telecom interface glue logic, and legacy system upgrades that previously used discrete TTL or 74-series glue logic. The 208-pin PQFP package provides a fine-pitch (0.5 mm) surface-mount footprint with gull-wing leads, simplifying PCB assembly on standard reflow profiles. When designing with the EPF6024AQI208-2N, ensure a stable 3.3 V core supply with proper decoupling, and always pair the FPGA with a configuration memory (EPC2, EPC4, or compatible). JTAG boundary-scan is supported via the 4-wire IEEE 1149.1 interface, enabling in-system programming (ISP) and post-assembly verification. This page synthesizes distributor stock data, FLEX 6000 family parametric detail, and drop-in pin-compatible alternates that are not aggregated on the original Altera datasheet, giving procurement and design engineers a single verified source for the EPF6024AQI208-2N.
EPF6024AQI208-3 - FLEX 6000 FPGA 24K Gates 208-PQFP | Intel
The Intel EPF6024AQI208-3 is a member of the FLEX 6000 family of Field Programmable Gate Arrays, integrating 24,000 gates and 1,960 logic cells in a 208-pin Plastic Quad Flat Pack (PQFP) package. Built on a 0.42 µm CMOS process and operating at 3.3 V core, the device provides 171 user I/O pins and is rated for commercial temperature operation, delivering up to 142.86 MHz internal performance. The FLEX 6000 family was engineered as an ideal low-cost, programmable alternative to high-volume gate-array applications and allows rapid design changes during prototyping or design testing. A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit whose logic resources, interconnect, and I/O cells are defined by a user-supplied bitstream after manufacture. FPGAs sit between fixed-function Application-Specific Integrated Circuits (ASICs) and software-driven microcontrollers in the digital design hierarchy: they offer hardware-timed parallelism and deterministic latency unavailable in sequential processors, while avoiding the NRE mask costs of ASICs. The FLEX 6000 series belongs to the broader Programmable Logic Device (PLD) family, which also includes CPLDs and SPLDs. Key features of the EPF6024AQI208-3 include a register-rich, Look-Up Table (LUT)-based logic architecture, OptiFLEX interconnect that minimizes die area for high logic utilization, four Embedded Array Blocks (EABs) for on-chip memory implementation, and built-in JTAG boundary-scan test support (IEEE Std 1149.1). Each logic element (LE) contains a 4-input LUT, a programmable register, and carry/chain interconnect, allowing efficient implementation of arithmetic, register-intensive, and combinatorial designs without external memory components. Architecturally, the device employs a continuous, row-and-column interconnect backbone (FastTrack) that routes signals across the die with predictable delay. The 3.3 V supply rail reduces power consumption by roughly 40 percent compared with the 5.0 V FLEX 8000 predecessors, while still supporting 5.0 V tolerant I/O through clamping diodes on input pins. Configuration can be performed via passive serial, active serial, or JTAG modes using industry-standard EPC configuration devices, enabling in-system reconfiguration for field upgrades. Typical applications span glue-logic consolidation in industrial control boards, peripheral bus interfacing (ISA, PCI, VME), high-speed data-pump controllers, DSP pre-/post-processing front-ends, and low-volume prototypes replacing mask-programmed gate arrays. Because FLEX 6000 silicon is mature and broadly second-sourced on the secondary market, the EPF6024AQI208-3 is also frequently specified for long-lifecycle aerospace, defense, and medical systems that were originally designed in the late 1990s. When designing with this part, observe that the 3.3 V core cannot be directly powered from a 5 V rail - a regulator is required. Inputs are 5 V tolerant via clamping diodes but prolonged overdrive can inject latch-up current; series resistors of 200–470 Ω are recommended on signals driven from 5 V logic. Decoupling follows the standard FPGA guideline of one 0.1 µF high-frequency cap per VCC/GND pair plus bulk capacitors of 10–47 µF at each supply pin group. This page aggregates distributor pricing, verified drop-in alternatives within the FLEX 6000 family, and practical design guidance not consolidated in the original datasheet, supporting both new designs and maintenance of long-life legacy systems.

The FLEX 6000 family was specifically architected as an ideal low-cost programmable alternative to high-volume gate array applications, enabling fast design changes during prototyping and design testing. Key features include the OptiFLEX architecture for high utilization, multiVolt I/O support for interfacing with 2.5 V, 3.3 V, and 5 V buses, in-system programmability through a dedicated configuration interface, and JTAG boundary-scan test support per IEEE 1149.1. The "3N" speed grade designation places this part in a specific performance bin optimized for typical commercial industrial temperature ranges. With 1,960 logic elements and abundant user I/O, the EPF6024AQI208-3N delivers substantial logic capacity for glue logic, bus bridging, and parallel DSP pre/post-processing tasks. From an architectural perspective, the FLEX 6000 family employs continuous, segmented routing interconnect combined with dedicated carry chains and cascade chains that accelerate arithmetic and wide datapath operations. The 0.42 µm four-metal-layer CMOS process delivers a balance of die density, static power, and 3.3 V tolerance that was industry-leading at product introduction. Typical applications include industrial control glue logic, telecommunications interface bridging, prototyping of ASIC designs, parallel peripheral controllers, and embedded system bus arbiters. The 208-pin PQFP package and 171 user I/O pins enable direct interfacing with wide parallel buses such as PCI, ISA, and external memory buses. When designing with this device, pay close attention to configuration mode selection and the configuration device interface, since the FLEX 6000 family supports both passive serial and passive parallel configuration schemes with EPC configuration memories. Designers should also verify supply decoupling on every VCCINT and VCCIO pin per the FLEX 6000 Device Family datasheet recommendations.

Key features include 1,960 logic elements, 199 user I/O pins, 4 dedicated inputs, embedded SRAM-based configuration memory, and an industrial operating temperature range of -40C to +85C. The 'AQI240' suffix denotes the plastic QFP package and industrial temperature grade, while '-2N' indicates the speed grade and lead-free (Pb-free) finish. Technically, the device uses a 5.0V-tolerant CMOS SRAM configuration cell with an EEPROM-less, ISP-capable architecture that loads bitstreams from external PROMs or microcontrollers. Its continuous routing fabric and FastTrack interconnect minimize routing congestion, while per-LE flip-flops and dedicated carry chains support efficient arithmetic and state-machine implementation. Typical applications include industrial glue logic, peripheral bus bridges (ISA-to-PCI glue, UART expansion), motor-control co-processors, telecom line cards, and legacy embedded-system replacement. The wide 199 I/O count makes it suitable for parallel-bus interfaces and high-pin-count control planes. When designing with this device, ensure an external configuration memory (EPC1/EPC2 or compatible PROM) is provided for SRAM cell loading on power-up, and respect the JTAG boundary-scan chain (IEEE 1149.1) for in-system programming. Plan PCB thermal dissipation because PQFP-240 packages have higher junction-to-ambient thermal resistance than BGA equivalents.

The 240-pin PQFP footprint enables simpler rework and breadboarding compared with fine-pitch BGA alternatives, an important consideration for legacy industrial designs. Architecturally, the FLEX 6000 device uses Altera's patented continuous interconnect scheme with embedded array blocks (EABs) used as RAM/ROM. The part is fabricated on a CMOS process and operates from a 5.0 V core supply with multi-voltage I/O support. Configuration is loaded from a serial or parallel PROM over a dedicated data path, making board-level bring-up straightforward. Typical applications include industrial control glue logic, parallel I/O expansion and bus interfacing, prototype-to-production ASIC replacement, motor-control sequencing, legacy telecom backplane glue logic, and test instrumentation I/O conditioning. The 240-pin PQFP package is also favored where socket-based field replacement is required. Design consideration: The EPF6024AQI240-3 is an older FLEX 6000 device, and Intel/Altera long-term support is limited. Designers building new products should consider Cyclone or Cyclone II as modern equivalents, while keeping the FLEX 6000 family for legacy repair and second-source maintenance.

The device interfaces with industry-standard configuration memories including the EPC1, EPC2, and EPC16 serial configuration devices from Altera/Intel. Typical applications include legacy industrial control systems, telecommunications backplane glue logic, parallel bus bridging, and prototype ASIC replacement. The wide I/O count and 5V tolerance make it especially well-suited to interfacing older microprocessors with modern peripherals. When designing with this FPGA, ensure your configuration memory interface is correctly wired and that the board supports the required JTAG programming path. The PQFP-240 footprint requires substantial PCB real estate and careful thermal planning for industrial temperature operation.

The Altera EPF6024ATC100-10 is a member of the FLEX 6000 family of CMOS programmable logic devices, offering 24,000 typical gates (16,000 logic gates equivalent) in a 100-pin TQFP (TC100) surface-mount package with -10 speed grade. The device is fabricated on a 0.42 um CMOS SRAM-based process and operates from a 3.3V core supply with 5.0V tolerant I/O, making it drop-in compatible with the older 5V-only MAX 7000 family while consuming substantially less power. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the density of gate arrays with the in-system reprogrammability of SRAM. Within the broader semiconductor taxonomy, an FPGA belongs to: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. FPGAs are used to implement arbitrary digital logic functions, glue logic, bus bridges, state machines, and parallel data-path circuits, sitting between fixed-function ASICs (high NRE, low unit cost) and small CPLDs (low density, non-volatile) in the design trade-off space. Key features of the EPF6024ATC100-10 include 1,960 logic elements (LEs), 24,192 RAM bits of embedded memory, four embedded array blocks (EABs) each configurable as 2Kx8 / 4Kx4 / 8Kx2 / 16Kx1 RAM or ROM, 80 maximum user I/O pins, and FastTrack continuous routing interconnect. Per the manufacturer datasheet, the device supports in-system configuration via the passive serial (PS), passive parallel asynchronous (PPA), passive parallel synchronous (PPS), and active serial (AS) configuration schemes with optional data compression for faster configuration. Architecturally, each LE contains a 4-input look-up table (LUT), a programmable register, a carry chain for fast adders, and a cascade chain for wide fan-in functions. The four EABs each provide 2K bits of true dual-port RAM with byte enables, enabling efficient FIFO, look-up-table, and small-cache implementations without consuming external LE memory. The FastTrack interconnect provides predictable, delay-driven routing across row and column channels, simplifying timing closure compared with segmented architectures. Typical applications include industrial control glue logic, telecom line-card bus interfaces, legacy peripheral bridging (PCI-to-ISA, UART-to-ISA), DSP co-processing front-ends, and digital instrumentation. The wide 5V tolerant I/O makes it a popular choice as a drop-in upgrade for 5V MAX 7000 designs that need higher density without redesigning the power tree. Designers should note that the EPF6024ATC100-10 is in the Altera FLEX 6000 family with -10 speed grade; the higher -2 and -3 speed grades (when available) offer improved Fmax but require verification against timing constraints. Quiescent supply current is dominated by I/O switching, so decoupling must include 0.1 uF X7R ceramics per VCCIO/VCCINT pin pair plus a bulk 33 uF tantalum near the supply pins.
EPF6024ATC114-3 - FLEX 6000 FPGA 24K Gates | Altera
The Altera (now Intel) EPF6024ATC114-3 is a member of the FLEX 6000 family of SRAM-based programmable logic devices, providing approximately 24,000 equivalent gates of logic capacity in a 114-pin TQFP package. It is a low-density, low-cost FPGA optimized for glue-logic, bus-interface, and high-volume consumer/industrial applications where ASIC replacement economics matter more than raw logic density. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing configurable logic blocks (CLBs), programmable routing, and I/O cells that engineers can program after manufacture using a hardware description language (HDL). In the broader taxonomy, FPGAs belong to programmable logic devices (PLDs), sitting alongside CPLDs and structured ASICs; the FLEX 6000 family represents Altera's earlier-generation, SRAM-based, look-up-table (LUT) architecture that was widely adopted in the late 1990s and early 2000s for ASIC prototyping and low-density glue logic. Key features of the EPF6024ATC114-3 include approximately 24,000 typical gates, 1,960 logic elements (LEs), 117 user I/O pins, and SRAM-based configuration with a 5.0 V tolerant I/O supply option.

Architecturally, the FLEX 6000 device uses a row-and-column interconnect structure with embedded array blocks (EABs) for memory and arithmetic functions. Each logic element contains a 4-input look-up table (LUT), a programmable flip-flop, and fast carry-chain logic for arithmetic. This is a different architecture from MAX 7000 (CPLD) and from the more modern Cyclone series, so designers porting designs between families must re-target HDL and re-pin assignments. Typical applications include bus-interface bridging, peripheral controllers, ASIC prototyping, industrial control glue logic, and legacy telecommunications backplane interfaces. The wide operating temperature range and PQFP/TQFP packaging also make it suitable for industrial automation systems and embedded instrumentation where surface-mount rework is straightforward. When designing with this part, note that the EPF6024ATC114-3 is now in an obsolete/EOL lifecycle state. Engineers targeting new designs should consider the modern Cyclone series or MAX II CPLDs, while existing production designs should verify long-term supply arrangements with distributors and consider last-time-buy opportunities. Configuration must be loaded from an external serial PROM at power-up because the SRAM-based configuration is volatile. This page synthesizes verified distributor inventory, drop-in pin-compatible alternatives from the FLEX 6000 family, and practical design notes for legacy ASIC replacement, providing context not aggregated in any single manufacturer or distributor datasheet.
EPF6024ATC144 - FLEX 6000 FPGA 24K Gates 117 I/O 144-LQFP | Altera

An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and programmable I/O cells. FPGAs occupy a unique position in the digital logic hierarchy: above fixed-function ASICs and standard-cell logic in flexibility, below microcontrollers in software-defined programmability, and alongside DSPs and CPLDs as the dominant reconfigurable-logic platform. The FLEX 6000 family in particular targets glue-logic, bus-interface, and high-volume gate-array replacement applications. Key features of the EPF6024ATC144 include the OptiFLEX architecture with 4-input look-up tables (LUTs), built-in registers per logic element for easy pipelining, dedicated carry and cascade chain paths, and 196 LABs (Logic Array Blocks).

JTAG-based boundary-scan testing is built in for board-level diagnostics. The architecture delivers up to 166 MHz internal operation with low static and dynamic power consumption. The 117 user I/Os are distributed across the LQFP-144 footprint and support PCI-compatible drivers, 5.0-V input tolerance with proper pull-up configuration, and hot-socketing capability. Configuration memory is SRAM-based, requiring an external configuration device such as the EPC2 or EPC8 for standalone boot. Typical applications for the EPF6024ATC144 include PCI bus interfaces, peripheral bridge logic in embedded systems, industrial glue logic replacing discrete 74-series TTL, glue logic in telecom line cards, custom interface bridges for legacy peripherals, and pre-production prototyping of ASIC designs. Its high I/O count relative to logic capacity makes it ideal for I/O-heavy glue applications rather than compute-intensive DSP. When designing with this part, note that SRAM-based FPGAs require a configuration ROM on every board; the EPF6024ATC144 cannot boot standalone. A 100 µF bulk capacitor plus 0.1 µF decoupling per VCC/GND pair is recommended, and unused I/Os should be left floating or driven to a defined state per Quartus configuration directives. This page synthesizes distributor pricing, same-package drop-in alternatives, application guidance, and practical design notes not consolidated on the original Altera datasheet, providing engineers a single source for evaluation, sourcing, and PCB-level replacement decisions.

Within the broader power-management/PLD hierarchy, FPGAs sit at the top of the programmable logic tree: PLD -> CPLD -> FPGA -> SRAM-based FPGA. The FLEX 6000 family uses a look-up-table (LUT)-based architecture with continuous FastTrack interconnect routing, distinguishing it from older PAL/GAL devices and from the non-volatile MAX series CPLDs. Key features of the EPF6024ATC144-13 include 24,000 typical gates, 1,960 logic cells, 196 LABs, 117 maximum user I/O, in-system programmability via the serial configuration EPROM interface, 5V-tolerant I/O on a 3.3 V core, and JTAG boundary-scan support. The -13 speed grade corresponds to a pin-to-pin delay of approximately 13 ns, making the part suitable for moderately fast control logic and bus-bridge applications rather than high-speed DSP pipelines. Architecturally, the device uses a hierarchical interconnect structure with row and column FastTrack channels that route signals between LABs. Each LAB contains 10 Logic Elements (LEs), and each LE carries a 4-input LUT, a programmable register, and a carry chain for arithmetic. Embedded array blocks (EABs) provide small memory primitives for FIFO and shallow RAM functions. Typical applications include industrial control glue logic, telecommunications interface bridges, peripheral bus adapters (PCI, ISA, VME bridges), motor-control sequencers, legacy system modernization, and low-volume ASIC prototyping where the 144-pin LQFP footprint is already designed in. The wide package and modest gate count also make it a popular choice for educational FPGA platforms and laboratory teaching kits. When designing with this part, ensure the configuration EPROM (EPC1, EPC2, or compatible) is correctly sized for the bitstream and that JTAG chain integrity is verified prior to in-system programming. Because the FLEX 6000 family is built on 0.42 µm SRAM cells, the bitstream is volatile - the device must be reconfigured on every power-up unless an external controller holds the part in reset until configuration completes.

EPF6024ATC144-14 - FLEX 6000 FPGA, 24K Gates, 144-TQFP | Altera
The Altera EPF6024ATC144-14 is a member of the FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs) housed in a 144-pin Thin Quad Flat Pack (TQFP) package. It integrates 24,000 typical gates (logic density), 1,960 logic elements (LEs) organized as 196 Logic Array Blocks (LABs), and 117 user I/O pins, making it a mid-density programmable logic solution for glue logic, bus interfacing, and state-machine-heavy designs in the late-1990s/early-2000s era. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that uses an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and programmable I/O cells to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy (PLD -> CPLD -> FPGA) and offer the highest logic density and richest feature set at the cost of higher static power consumption and configuration memory requirements. The FLEX 6000 family uses a look-up-table (LUT)-based LAB architecture with SRAM configuration memory, requiring an external configuration ROM on power-up. Key features of the EPF6024ATC144-14 include: 1,960 LEs, 196 LABs, 117 user I/O pins, typical operating frequency up to 200 MHz at the -3 speed grade, and 5V-tolerant I/O on a 3.3V core supply. The -14 speed grade denotes the slowest commercial grade, targeting cost-sensitive industrial and consumer applications where clock rates below 100 MHz are acceptable. The 144-pin TQFP package is a plastic surface-mount form factor with 0.5 mm lead pitch and a 22 mm x 22 mm body, designed for standard SMT reflow assembly. The FLEX 6000 architecture uses a four-input LUT-based logic element, a hierarchical interconnect with FastTrack continuous routing, and embedded memory. The 1960-LE capacity is sufficient for medium-complexity glue logic, peripheral bridges, custom bus controllers, and instrumentation front-ends, but is now considered low-density by modern standards. Typical applications include industrial motor-control interfaces, telecommunications line cards, custom peripheral bridges in legacy embedded systems, test and measurement backplanes, and ASIC prototyping. The 117 I/O pins support wide parallel buses (16-bit or 18-bit) common in legacy parallel interfaces such as ISA, PC/104, and VME. When designing with this device, note that the FLEX 6000 family is mature and Intel/Altera recommends the MAX II or Cyclone series for new designs; the EPF6024ATC144-14 remains useful for long-lifecycle products, EOL bridge buys, and existing board repairs. Configuration requires an EPC configuration device or microcontroller-based configuration mode.

EPF6024ATC144-15 - FLEX 6000 FPGA, 24K Gates, 117 I/O, 144-LQFP | Intel (Altera)
The Intel (formerly Altera) EPF6024ATC144-15 is a member of the FLEX 6000 family of CMOS field-programmable gate arrays (FPGAs) that delivers 24,000 typical gates, 1,960 logic elements (LEs) organized as 196 logic array blocks (LABs), and 117 user I/O pins in a 144-pin LQFP (TBC) surface-mount package with a -15 speed grade. A field-programmable gate array (FPGA) is a reconfigurable integrated circuit that combines programmable logic blocks, programmable interconnect, and programmable I/O cells on a single semiconductor die. The FLEX 6000 family targets low-cost, high-volume gate-array replacement and rapid prototyping; within the broader semiconductor taxonomy it sits as a sub-class of programmable logic devices (PLDs) alongside CPLDs and structured ASICs. Key features of the EPF6024ATC144-15 include a 3.3 V core supply, in-system programmability via SRAM configuration cells, built-in carry and cascade chains for high-speed arithmetic and wide-input functions, JTAG-compliant boundary-scan test support, and multi-voltage I/O banks. The -15 speed grade denotes a specific AC-timing bin within the FLEX 6000 family, where lower numeric values indicate faster timing. Architecturally, the FLEX 6000 fabric is built from SRAM-based look-up tables (LUTs) that drive a four-input combinational function, with a dedicated register for sequential logic. The carry chain supports fast counters and adders, while cascade chains connect LEs 2 through 10 in each LAB and all LABs within the same half-row, enabling minimum-delay implementation of wide-input functions. Typical applications for the EPF6024ATC144-15 include glue-logic integration in industrial control boards, telecommunications line-card controllers, bus-interface bridging (PCI, ISA, VME bridges), prototyping of gate-array designs, and replacement of discrete TTL/CMOS logic clusters where fast design changes are needed. When designing with this device, confirm configuration mode (PS, PPS, AS, JTAG), supply decoupling (at least 0.1 µF plus bulk per rail), and unused-pin handling (drive to a defined logic level or use the Quartus/MAX+PLUS II "Enable All Pins as Inputs" option to suppress spurious toggles).
